The right B2B Google Ads keywords are the ones that bring in buyers your sales team wants to talk to. Search volume and cost per click tell you what the traffic costs. They don’t tell you who it is.
The first search terms review on a new account is usually the most revealing hour of the engagement. We sort the report by spend, and near the top sit queries no buyer would type: free versions of the product, jobs at companies in the category, certification courses for people learning the field. Each one cost real money, and some of them filled out a form.
None of that shows up on a dashboard that reports clicks and cost per lead. It shows up weeks later, when sales works the leads and finds students, job seekers, and people hunting for a free tool. The problem started with the keywords, which makes keyword selection a lead-quality decision long before anyone reaches the landing page.
This article is part of The Complete Guide to Google Ads for B2B Lead Generation and covers how to choose keywords by the buyers they produce, how to read search intent, and how match types and negative keywords keep the account pointed at the right people.
Which Buyers Are You Willing to Pay For?
Start with the buyer situations your company can serve profitably, then find the searches those buyers make. A keyword belongs in the account when its likely searcher, their need, and the next step you can offer all line up.
Before volume enters the conversation, pressure-test each keyword theme against four questions.
- Does the query describe a problem your product or service actually solves?
- Would the likely searcher have influence over a purchase, evaluation, or shortlist?
- Does the wording suggest a business use case, or a consumer, student, job seeker, or do-it-yourself need?
- Can the landing page keep the promise the search implies?
A high-volume term that fails those questions is expensive noise. A lower-volume term can matter a great deal when it consistently reaches the right accounts and produces real sales conversations. Would your sales team recognize the buyer behind each of your top five keywords by spend?
Recommendation
Write down the buyer a keyword is supposed to attract before you approve it. The note gives marketing and sales something concrete to check once the leads arrive.
Research Searches Need a Different Offer Than Buying Searches
Research-stage and buying-stage searches can both support demand generation, but they do different jobs and deserve different expectations. Buying intent can justify a direct path to a sales conversation. Research intent needs an offer and a measurement plan that fit an earlier stage of the decision.
| Intent signal | What the searcher is doing | How to judge it |
|---|---|---|
| Problem research | Defining a problem, cause, or possible approach | Qualified engagement and later pipeline influence |
| Category evaluation | Comparing solution types, capabilities, or vendors | Sales-qualified leads and opportunity creation |
| Purchase intent | Seeking pricing, a provider, a demo, or a specific solution | Opportunities, acquisition cost, and revenue contribution |
| Wrong-fit intent | Looking for jobs, definitions, free tools, or consumer help | Exclusion unless evidence proves business value |
Research terms aren’t automatically weak. They turn wasteful when the ad asks for a sales conversation the searcher isn’t ready to have, or when the team reports early engagement as if it were pipeline. A trade show booth works the same way. The person browsing the aisle and the person asking about pricing both matter, but you wouldn’t hand them the same brochure or count them the same way afterward.
Reading a search terms report for intent
The search terms report shows what people actually typed before they clicked. Here is how a review might sort six queries for a company that sells project management software to mid-sized engineering firms. The queries are illustrative.
| Search term | What it signals | Decision |
|---|---|---|
| project management software for engineering firms | Category evaluation from the right industry | Keep and protect budget |
| project management software pricing | Purchase intent | Keep and send to a page that answers pricing |
| free project management software | Wants a free tool | Add “free” as a negative unless a free tier converts to paid |
| project manager jobs | Job seeker | Add “jobs” and “careers” as negatives |
| pmp certification course | Learning the field | Add “certification” and “course” as negatives |
| [your brand] login | Existing customer looking for the app | Add “login” as a negative |
One of the first leaks we find in an account is that last row. Existing customers search for the login page and click a paid ad to get there. It costs money every day and buys nothing new.
Judge Keywords by the Pipeline They Produce
A B2B keyword earns budget through the quality of the demand it creates. CPC and conversion rate are useful operating signals. Cost per SQL, cost per opportunity, and eventually customer acquisition cost decide whether the traffic is worth buying.
- Confirm query relevance. Review the actual searches behind each keyword theme and identify which buyers are entering the account.
- Compare lead quality. Separate accepted leads from spam, poor-fit companies, students, vendors, and people outside the buying process.
- Trace qualified outcomes. Connect campaign and keyword context to SQLs and opportunities in the CRM.
- Make the budget decision. Expand, constrain, or pause the theme based on what it contributed downstream.
A worked example
Consider two keyword themes in the same account over the same month. The numbers are illustrative.
| Measure | Theme A: broad category term | Theme B: specific solution term |
|---|---|---|
| Cost per click | $18 | $42 |
| Spend | $18,000 | $12,600 |
| Leads | 60 | 20 |
| Cost per lead | $300 | $630 |
| Sales-qualified leads | 6 | 8 |
| Cost per SQL | $3,000 | $1,575 |
| Opportunities | 1 | 4 |
| Cost per opportunity | $18,000 | $3,150 |
On a CPC or cost-per-lead report, Theme A looks like the better buy. On a cost-per-opportunity report, Theme B is more than five times as efficient. A keyword report that stops at the lead is grading the wrong test.
This view depends on CRM data that can tie opportunities back to campaigns and keyword themes. If yours can’t yet, the CRM section of our pillar guide covers what to fix first.

When Are Competitor Terms Worth the Cost?
Competitor terms are worth the cost when the searcher is still shopping. Someone who searches a competitor’s name on its own usually knows what they want. If you search for Nike running shoes and an Adidas ad appears, you probably keep scrolling. B2B buyers behave the same way.
The value sits in the modifiers. Searches like “[competitor] alternative,” “[competitor] vs,” or “[competitor] pricing comparison” come from someone actively weighing options, and that buyer may welcome a credible reason to look at you. We often find competitor campaigns that look efficient on form fills and rarely produce an opportunity. Build competitor coverage around the shopping modifiers, and judge it on opportunities like any other theme.
Your own brand terms answer a different question. Our guide to Google Ads account structure covers why they belong in their own campaigns.
Match Types Decide How Far Google Can Expand a Keyword
Match type determines how far Google can move beyond the keyword wording to find related searches. Exact match offers the most control, phrase match reaches more searches that carry the keyword’s meaning, and broad match uses additional signals to expand further, according to Google’s keyword matching documentation.
| Option | What expands | Leadership question |
|---|---|---|
| Exact match | Searches with the same meaning or intent | Do these tightly framed searches produce qualified demand? |
| Phrase match | More searches that include the keyword’s meaning | Which additional contexts help or hurt lead quality? |
| Broad match | Related searches using account and user signals | Is the negative keyword list and search term review strong enough to govern the wider reach? |
| AI Max search term matching | Broad, asset-based, landing-page-based, and keywordless matching | Can the team isolate incremental reach and judge its pipeline quality? |
We consistently see broad match pull in overlapping searches that aren’t relevant to the target audience. We still use it in some cases, but only with a large, actively maintained negative keyword list and someone watching the search terms report closely. It takes real work, and the result isn’t always worth it.
Google describes AI Max for Search as a set of features inside Search campaigns that broadens search term matching and customizes assets. We’re testing it and haven’t reached a conclusion either way, so we treat any rollout as a measured test with a baseline and a lead quality review. Performance Max raises a separate set of quality questions, covered in our pillar guide.
Negative Keywords Are Lead Quality Controls
Negative keywords keep searches you’d never want to pay for out of the auction. Treat the list as a quality control that protects sales capacity, and build it from the wrong-fit demand that actually shows up in search terms and sales feedback.
For a leadership review, four categories matter most.
- Audience exclusions: jobs, careers, courses, certification, student, and consumer language when those groups can’t buy.
- Offer exclusions: free, template, or download terms when your commercial model doesn’t support that expectation.
- Use-case exclusions: industries, company sizes, locations, or applications the business can’t serve.
- Meaning exclusions: alternate definitions and adjacent categories that share vocabulary with your offer.
Precision matters here. Google’s account-level negative keyword guidance notes that negative keywords don’t match close variants or other expansions, so a singular, plural, or related form may need its own entry. Check what actually served instead of assuming one negative covers every version.

Frequently Asked Questions
Sometimes, but it takes work. In our experience, broad match consistently pulls in searches outside the target audience, so it needs a large negative keyword list, close search term reviews, and conversion data reliable enough to steer it. We use it selectively, not as a default.
Usually only with shopping modifiers. A bare competitor name typically comes from someone who has already chosen, while searches like “[competitor] alternative” or “[competitor] vs” come from buyers still weighing options. Judge competitor campaigns on opportunities, not form fills.
Track each keyword theme through to sales-qualified leads and opportunities, then compare cost per opportunity. A theme with a higher CPC can win once lead quality is counted. This requires CRM data that ties opportunities back to campaigns, so confirm that connection first.
Start with job seekers, students, and people looking for free tools, using terms such as “jobs,” “careers,” “course,” “certification,” and “free.” Then add industries, company sizes, and locations you can’t serve, plus alternate meanings of your category terms. Existing customers searching for a login page belong on the list too.
Put Your Next Search Terms Review to Work
Pull last month’s search terms report, sort it by spend, and mark each of the top 50 queries as buyer, maybe, or never. The never pile is your first negative keyword list. The maybe pile is where your pipeline data has to make the call.
